A 2.5V/12b/30MS/s randomly time interleaved ADC system has been implemented. Using this circuit an earlier presented [6] blind gain error equalization method has been verified. It is verified that the gain in each ADC unit can be found and equalized by using the blind estimation method, since the randomization assures that there is no correlation between the ADC unit used and the input data. It has been found that the blind gain error equalization attenuates the energy of the gain distortion tones by up to 72 dB. The SNDR of the random time interleaved ADC system was improved by 10.1 [dB] after the amplitude offset and gain equalization was performed. The measured system SNDR is only 2.1 [dB] worse than the measured SNDR of a single ADC unit
